Patented Mar. 26, 1935 UNITED STATES PATENT OFFIQE PACKAGE Walter K. Miller, Chicago, Ill.-, assignor to Shellmar Products Company, Chicago, Elk, a corporation of Delaware The present invention relates to packages for containing materials of various sorts, and has particular reference to improvements in packages having. a cardboard backing and a facing sheet of transparent cellulose sheeting or a similar material.

A principal object of my invention is the provision of a package which is compact, sturdy, and easily filled with the desired materials.

An additional object is to provide a package which may be closed in a ready and permanent manner.

Still another object is the provision of a package having closure ends folded over and secured by a label which extends the length of the package.

These and other objects will become apparent from a consideration of the following description and by reference to the accompanying drawing, in which Fig. 1 is a front view of a package made in accordance with my invention;

2 is a rear view of the package shown in Fig. 3 is a cross-sectional view taken along lines 3-3 fFig. 1;

Fig. 4 is a cross sectional view of the package shown in Fig. 3 filled with strips of bacon; and Fig. 5 is a sectional view taken along lines 5--5 of Fig. 4:.

In the drawing, 1 represents a cardboard backing which is ordinarily of rectangular shape. The facing sheet 2, which is preferably made of a transparent cellulose film or sheet such as the product known as "Cellophane f has attaching portions 3-3 folded over and adhesively secured to the back of the cardboard 1 and along the edge thereof. The facing is extended beyond the ends of the cardboard backing to form closure portions 4 and 5. As shown in Figs. 1 and 2, the closure portion 5 has been folded over and against the cardboard backing. For inserting the material to be packaged, it is, of course, necessary that at least one of the ends be left open. Ordinarily, there is no need for allowing both ends to remain open and, in fact, for packaging some materials, it is essential that one of the ends be closed. The facing is of necessity larger than the cardboard backing and in order to provide a collapsible package, the sides of the facing are preferably provided with one or more accordion plaits, as shown in-Fig. 3. Other types of folding may also be employed, but for purposes of folding over-the ends or closure portions'of the cellulose facing material and securing the same'to the back of the package, the accordion type of folding has been found preferable.

In accordance with my invention a label 6 is adhesively secured'to the back of the cardboard and the attaching portions of the facing. How- 5 ever, the label is provided'at its ends-with sealing portions '7 and 8 which e not glued to the cardboard backing. As she in Fig. 2, the sealing portions are free to be rotated upwardly about the portion of the label which is adhesively at- 10 tached to the cardboard. In this manner the. sealing portions may be lifted up and the closure portions of the facing may then be folded over against the cardboard backing. The sealing por tions of the label are provided with an adhesive 15 such as a remoistening glue and a permanent closure for the package is made by moistening the sealing portion and pressing it against the: folded-over ends of the cellulose facing.

For packaging certain materials, such as bacon, 20 it is desirable that the .cellulose sheeting be of the greaseand moisture-proof type. As greaseproof cellulose material does not cohere with a remoistening glue, it is desirable in such cases that a solvent for the material be employed to eflect a union between the sealing portion of the label and the folded-over ends of the facing.

The continuous label materially assists in rendering the base of the package grease and moisture-proof. It also provides a means by which all closure parts of the package are neatly hidden from view. It is possible with this type of package to print identifying data on the label portions prior to securing the same to the back of the package. Consequently, it isnot necessary to make up the packages according to each individual order. Instead, all the packages may be made up alike, and individual orders distinguished by a mere change in labels.

Modifications coming within the spirit of my invention are intended to be included in the appended claims.

I claim: 7

1. A package of the type described, comprising a cardboard backing member, a sheet of cellulose I cellulose sheeting to the back of the cardboard member providing a seal therefor, one of said closure portions being unfolded and one end of said label being unsealed, whereby when the package is filled the unfolded closure portion may be folded over adjacent the back of the cardboard member and the unsealed end of the label may be sealed thereover to seal said package and to reinforce the latter substantially throughout its length.

2. A package of the type described, comprising a cardboard backing member, a sheet of cellulose sheeting forming a facing for said package and having its side portions turned over and secured to the back of said cardboard, closure portions on said cellulose sheeting extending beyond the ends of said cardboard and being folded over adjacent the back of said cardboard in closed position, said facing and said closure portions being provided with a bellows fold on the upper side of said cardboard backing member, and a separate label adhesively secured to and constituting a complete closure for the major portion of the bggk of said package, said label securing the fold over closure portions of the cellulose sheeting to the under side of the cardboard backing member providing a seal for said'closm'e portions including the bellows fold therein, one of said closure portions being unfolded and thecorresponding end of said I label being unsealed, whereby when the package is filled the unfolded closure portion may be folded over adjacent the under side of the cardboard backing member and the unsealed end of the label may be sealed thereover to seal said package and to reinforce the latter substantially throughout its length.
